Answer:
2: Liquid
Step-by-step explanation:
Liquid has no shape (think of pouring water from a bowl to a cube, it doesn't keep the same shape) but has the same volume (from bowl to cube is still the same volume)
Hope this helps, have a nice day :))
There are some people disagreeing with me, so here are the others:
(which is totally okay, just wanted to clear it up!)
Solid: Has a definite shape and a definite volume (a cube will stay a cube)
Liquid: Has no shape, but definite volume (will change shapes but has same volume) (answer)
Gas: No shape, no volume (will change shapes, but also does not have a set volume)
Plasma: No shape, no volume (ionized gas)
